Shooting

Lens
'5

With
a Canon
FD
lens, metering
is
done
with
the
lens diaphragm at its
widest
opening. This is
called
"full-aperture
metering."
Stopped-down
Metering
With
a Canon
FL
lens, the TS
35mm
lens or any
other non-FD
lens, full-aperture metering is
not
possible. The lens
must
actually
be
closed (stop-
ped down)
to
the shooting aperture
for
metering.
This is
called
"stopped-down
metering."
In
stop-
ped-down
metering, the lens diaphragm will
open or close
as
you turn the aperture ring.
1. Push the
stop-down
lever towards the lens
until
it locks.

2. Make sure the shutter speed selector dial is
NOT on "PROGRAM."
3.
While pressing the shutter button, turn the
aperture ring
until the
stopped-down
metering
index and 5.6 appear. Correct exposure can-
not
be
obtained
with
any
other
display.
4. Press the shutter button
all
the way
down
for
exposure.
Notes
1.
Stopped-down
metering is not possible when
the shutter speed
selector dial is set
to
" PROGRAM."
2. You can also press the exposure preview
switch and turn the shutter speeed
selector
dial
until the stopped-down metering index
and 5.6 appear.
3.
Once the lens is stopped
down
, you can check
depth
of
field visually simply by inspecting the
subject through the viewfinder.
